I never thought owning a CNC machine was possible until I stumbled upon the Openbuilds site. After viewing numerous builds I was drawn to the Ox by Mark Carew but ultimately decided on a build of similar design, Halloumi by Savvas. It's a C-beam design driven by Nema 23 steppers with Acme lead screws. Like Savvas I will be fabricating temporary plates to get up and running then use the machine to mill the final plates. The material I'm using for the temp plates is solid surface (Avonite).

SLA resin printer based on a gen3/4 iPad Retina display. The design intent is to create a printer with the highest resolution possible with a lower cost of entry compared to DLP projector based SLA printers.

My build is based on many different builds but pieced together into a unit specifically to suit my needs. The footprint, without motors, is around 500mm x 1000mm with a gantry height of around 250mm. I used a combination of C-Beam, for the linear transmission, and V-Slot for the base and gantry supports. Forged angle connectors were used for attachment and I utilized the C-Beam gantry cart kits with anti-backlash blocks for both Y axes, the X axis, and Z axis.

This is my first CNC router build, so I started with the OpenBuilds C-Beam Machine XLarge mechanical bundle, including four high torque stepper motors. I took my time with the mechanical build, sought and found some great help for my control system, and designed and built a custom cabinet to house everything.

This is a C-Beam based router with V-rails used for the bed, a Sherline spindle with Jacobs chuck, closed loop stepper motors on every axis and an offline 4-axis CNC controller. A U-channel was created to guide the drag chain on the X-axis.

This easy to build actuator is configured to have not only strength, but accuracy! This low profile option offers endless possibilities, and we cant wait to see how this actuator is implemented in your build ideas!

A home-made CNC-machine with a 1.5 kW air cooled spindle motor suitable for milling materials such as wood, plastic and soft metals. The work table is 650 mm wide by 700 mm deep and the maximum movement is set to 560 mm for the x-axis, 480 mm for the y-axis and 105 mm for the z-axis.

This is my first foray into CNC machines, after much review I decided on the C-Beam machine as it seemed easy to work with and will enabled me to build more and larger machines as I gain knowledge. I am planning on building the machine largely unmodified from the reference design.
I will be building the machine an axis at a time as I need to spread out costs over time.

Contained within are links to our OpenBuilds sponsored C-beam Machine live build taking place at MRRF 2018 (Midwest Reprap Festival) on March 24 and 25, 2018. There will also be some build images and a few 3D printed STL items that were added.

My goal was to be able to enlarge my C-Beam with as many original parts as possible. I was able to recycle almost all of them with a only the two 500 mm rails left over. I used 1000 mm rails for the X Axis and I added another complete Y Axis assembly. I chose to keep it simple and I am very happy with the result!

A stable CNC Router that allows me to cut and carve bigger Parts.
The Machine is an original Build from Kyo's Sphinx CNC Machine. Thanks for the great Work and the Effort Kyo. Your Files and Lists helped me a lot to build that Sphinx 1x1m.

I built a CNC Router using 3/4 MDF, 1/8 aluminum angle for bearing races and various other odds and ends. I learned a lot about how not to build a CNC router. I found Openbuilds.com and decided to build a C-Beam for my first build.
The long term idea is to use this machine to build custom plates for and OX type machine and a 3d printer.

So we have new plates, stronger motors, belt drive reduction, but what should we do with them? In this article you might find the answer you were looking for as we took an “old” C-Beam machine and started to upgrade the X/Z body and added more torque and precision to the Z-axis.

The C-Beam Prefab Untitled is designed as the cartesian compliment to the C-Beam XL. With the exception of requiring a couple more 1000mm C-Beams and lead screws, the build requires a minimum of additional parts. The primary intention of the build is to maximize the cutting envelope while still staying within the sweet spot for C-beam rigidity. This design can easily be modified and allows for further custom structural components to be cut with the initial build platform.

Overview of my experience building the C-Beam Machine XL from OpenBuilds, along with updates as I move along and get it going. My application is for creating plates needed for lab functions, 19 rack bay covers, and whatever else arises.

This built is to convert an existing 500x500 C-Beam Machine into 1000x1000. Inspired by several builds including C-Beam Machine : (http://www.openbuilds.com/builds/c-beam%E2%84%A2-machine-plate-maker.2020/) and Gino's build : (http://www.openbuilds.com/builds/c-beam-gtc.3250/)

I started this build about 2 weeks after the c-beam hit the store. I purchased a single bundle and ordered a TinyG to run it. where I work I have Hardware, Software and Mechanical engineers and they all got sucked into my project. they want one to do prototyping at the office, once they see mine...

The build is based on a 500mm C-Beam and the SeeMeCNC FlexVat. The C-Beam is both the linear motion and a structural element of the design. The frame that holds the 45 degree first surface mirror and the build vat can slide up and down the C-Beam to accommodate projectors with lenses at different elevations.

The C-Beam Evolution is an evolving machine. The MkII is inspired by Kyo's C-Beam Spinx but currently uses my own design of plates made of 8mm acrylic (X-axis ends) and 6mm polycarbonate (Y axis ends). The plates were made on the MkI but I hope to be able to make 6mm aluminium plates on the MkII for the MkIII.

A C-Beam router made almost entirely of standard parts. Electronics include an xPro v2 board and NEMA 23 motors. Cuts are made with a small 300W DC spindle. A pressure foot is used to minimize the need for workholding.

This CNC utilizes the C-BEAM extruded aluminum for the "X", "Y", and "Z" axis. The gantry will move similar to the OX along with the "Z" except I am incorporating the C-BEAM instead of the 20x60 V-RAIL. To make the system as strong as possible I am using two C-BEAM rails back to back. The "Y" axis will encompass two sets of roller on both side of the C-BEAM extruded rails for added strength. All of the plates for this were created using the C-BEAM machine I completed several month ago.

My first ever build. Straight C-beam with tinyg controller a few do-dads and some make do choices.
Non-metric length lead screws to save long lead time. Jog knobs to cover the extra length and also practical.
My old Bosch Colt never had it so good.
Build out work remains, wire dressing, drag chain, vacuum, permanent base, etc.

This machine is fantastic. Teamed up with Fusion 360, Inkscape, and GrblPanel, I'm well on my way towards making at least one Christmas gift this year. I had some frustrating times during the build, mainly with getting everything to go together square, but overall it was fun. I can see that I'm going to need to be a bit creative in order to max out the work area for this machine so that I can produce the product I bought it for, but it will be able to do so much more for me as well.

This is a CNC Line Boring Machine for our cabinet shop. It drills the holes every 32 mm for the adjustable shelf pins in the cabinet side pieces. I chose this option over purchasing a multi-head boring machine that requires 11 drill bits - Left & Right hand twist - that also requires a lot of strength to plunge that many drill bits into the wood to be drilled.

A design in progress, to 3D carve two-part Aluminium injection moulds for Soft Plastic Lures and Lead Jigs, so I can prototype some of the concepts rattling around in my head.
All Openbuilds parts where possible, 1000x500mm footprint, 0.8kw Water-cooled Spindle?, High Torque Stepper?,Smoothieboard?, I still have no idea.
As a newbie to the CNC world, any wisdom would be welcome to take this from just a idea into reality so I can start playing with all this awesome stuff.
Thanks in advance

My first build was with the basic C-Beam Build. I soon found the z clearance a little constricting So I added 2 500 mm actuators to support the x axis rail . I also left off the front and back y axis support rails for easy cleaning. I mounted the base of the machine to 1/2" mdf with 10/32 screws and blind nuts.

The UltiBots CB3030 CNC uses C-Beam, V-Slot and an extruded aluminum T-Slot work table. This allows 6mm T-Nuts, step clamps and blocks to secure materials to the work surface. The all metal design makes the use of a mister possible.

This is a variant of a typical OX (Mark Carew inspiration) router using C-Beams/8mm Acme rods to drive all three axis. I went with a 1000mm x 1000mm frame size. Useable space is 28" (711mm) X 26" (660mm) with a Z axis work travel of approx. 3.25" (82.5mm).
A TinyG is used as a controller along with Fusion 360/Chilipper as the software for generating and running gcode files.

Per the special notes its a variant of the C-Beam, Machine.... I have noticed that alot of people build a CNC router to cut parts for other larger CNC machines.. eg Delta Printers etc....plus this will enable me to cut parts for model RC plans UAV's etc...
